Thereupon an earthquake overtook them: and then they lay lifeless, in their very homes, on the ground.

So the earthquake took them unawares, and they lay prostrate in their homes in the morning!

So the earthquake seized them, and morning found them prostrate in their dwelling-place.

So the earthquake seized them, and they were motionless bodies in their abodes.

So the earthquake seized them, and they became within their home [corpses] fallen prone.
